MANUFACTURING COMPANY, A COR- INTEGRAL CAB-FRAME STRUCTURE.

Application filed August 22, 1922. Serial No. 583,564.

To all whom it may concern:

Be it known that we, FRANK-"L. ALBEN, a citizen of the United States, and a resident of Wilkinsbur in the county of Allegheny and'State of ennsylvania and HAROLD A. HoUs'roN, a citizen of the United States, and a resident of Wilkinsbur in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Integral Cab-Frame Structures, of which the following is a specification.

Our invention relates to electric-railway vehicles and more especially'to supportingframe structures for vehicle bodies. Y

It is among the objects of this invention to provide an electric-locomotive-cab frame. which shall be of rigid, durable'and simple mechanical construction.-

It is a further object of this invention to provide a'cab frame which shall be. relatively simple and inexpensive to manufacture.

Heretofore, it has been customary practice to construct locomotive cab frames of structural parts requiring fitting, machining, assembling and riveting or the like. Usually, several castings and channel members were employed to produce such a body structure, which involved considerable expense and labor.

Our present invention is directed to a loco motive-cab-frame structure comprising a single integral casting which is adapted to be supported'upon a plurality of wheeledtruck members. The unitary structure comprising the side-frame portions, cross-ties, center bearings and aisle frames simplifies manufacture and greatly reduces the cost thereof besides providing arigid lightweight and mechanically durable construction.

In the accompanying drawings, constitut-- ing a part hereof and in which like reference characters designate like parts.

Figs. 1 and 2 represent fragmentary plan front and rear views, respectively, of a locomotive-cab-frame structure made in accordance with this invention;

Fig. 3 is a cross-sectional view taken along the line II IIII of Fig. 1, which is the preferred form of side-frame cross-section;

Fig. 4 is a sectional view corresponding to Fig. 3 but showing a different form of sideframe section, and

Figs. 5 and -6 are cross-sectional views illustrating modified the cab frame on the bearing plates 3 and 4 adapted to be pivotplurality of truck memcross-sectional views of endportions of the front provided with bumpers ally mounted on a bers shown in the Figs. 3 and 6. The and rear trucks are 5 and 6, tending parallel with the s secured thereto by verse-1y projecting brackets 8. A hinge. 31, connecting shown at the upper end of Fi 1.

The center-bearing plate 3%Figs. 2 and 6) is provided with an opening 9 adapted to receive a center pin .10 which is rotatably mounted in a center bearing 11 provided in a cross-tie 12 of the s'upportin truck. The center-bearin plate 4 (Fig. 1 is provided with an annu ar recess 13 (Fig. 3) adapted to receive a center pin 14 which is rotatably mounted in a split block 15 movably secured to a guide 16 constituting an integral part of the truck cross-tie 12.to provide longitudinal movement of' the block with the truck. This relative longitudinal movement of the truck and cab frame is necessaryfbecause ide frames 1, is

and VI-VI, respec respectively. An aisle frame 7, ex-- a plurality of transa pair of supporting trucks, is

of the cording of the cab under frame 'when the trucks pass over a curve. 1

Referring to Fig. 3, the side frames 1 are preferably of substantially box-shape in cross-section having a longitudinal recess 18 formed therein which reduces the weight of the members to a minimum and yet provides adequate strength. The side frames illustrated in Figs. 4 and 5 are of different crosssection but all of these are recessed longitudinally to combine minimum weight with maximum strength. In Fig. 3, the Shh frames 1 are provided with a plurality of longitudinally spaced side-bearing blocks 19 having ahorizontal plane bearing surface 2 adapted to seat on correspondingly shaped bearings 21 secured to the truck cross-ties 12 which are mounted on the truck side frames 22 that are j'ournaled to'the Although it is common practice to support the cab structure on the center bearings 8 and 4, it is proposed that the side bearings 20 and 21 serve as the main supporting area, thus providing for a more uniformdistribution of the load and stresses in. the cab frame and the supporting-truck structure. The side frames 1 (Fig. 3) are adapted to'receive'a motor housing 24: having projecting seating flanges 25 which are secured thereto in a suitable manner.

Referring to Fig. 5, a. cross-equalizer arm 27 ,pivotally mounted on'one of the crossties 12 of the truck by an equalizer pin 28, is supported on its ends by spring-hangers to the drive springs 29 which are SllPPOLtQtl over the driving box (not shown) by saddles 30.

It will be readily seen from the above description of our invention that locomotive beds constructed in accordance therewith provide rigid and mechanically durable structures readily adapted to manufacture, with the elimination of various operations and expense heretofore necessary in semirigid frame structures. It will also be obvious Ihat such unitary body support diverts thrusts and stresses from the motorgenerator sets and other apparatus mounted thereon.

i ilthough we have described a specific embodiment of our invention, it will be obvious to those skilled in the art that various changes may be made in the details of construction, as, for instance, the general design of the frames, reinforcing supports, center, side bearings and the like may be modified-to suit any given condition of cab or truck design in accordance with operating requiements. T he cross-sections illustrated in'Figs. 3-, 4, 5and 6 may be modified in their general shape and outline to accommodate any condition of stressing or loading, and the method of mounting the bed on the supporting trucks may be ac complished in any suitable manner.

These and other changes may be made without departing from the principles herein set forth.

We-claim as our invention:

-1. A supportingframe for vehicle bodies comprising an integral casting having Iongitudinal side-frame, tic-rod, center-bearing and aisle-frame portions.

2. A supporting frame for vehicle bodies comprising an integral'casting having longitudinal side-frame, transverse tie-rod, center-bearing and aisle-frame portions and having a plurality of side-bearing supports formed integral therewith. v
